Alzheimer's Disease Assessment Scale-Cognition (ADAS-cog)
Please visit this website for more information about the instrument: Alzheimer's Disease Assessment Scale-Cognition
Supplemental: Parkinson's Disease (PD)
Short Description of Instrument
The Alzheimer's Disease Assessment Scale- Cognition (ADAS-cog) was developed specifically to address selected aspects of cognitive function in Alzheimer's Disease (AD). The 11-item scale is designed to address language and memory skills in AD patients.
Construct measured: Cognition (specific for: memory, language, praxis).
Generic vs. disease specific: Designed specific to Alzheimer's disease.
Means of administration: Rater administered paper and pencil. Training required.
Intended respondent (e.g., patient, caregiver, etc.): Patient.
Scoring: maximum: 70; higher = worse cognition.
